[Feature]: ViewRenderingTestCase should support setting a pageowner for resources

[jdalsem]

Describe the feature

Currently we view test some resources. With route middleware like pageowner gatekeepers we define the requirement of a available pageowner in the resource. These resource will almost never check for the existence of a pageowner as it is enforced in the gatekeeper.
The testcases however do not set a pageowner, so testing these resources will fail.
